Snowpack Summary

5cm of snow fell in the Coquihalla a few nights ago and has buried a thick layer of surface hoar on most sheltered and shady slopes, but no new snow further north means it's still on the surface. This surface hoar may be sitting on a crust in sun and wind exposed areas making it especially touchy as soon as a sufficiently deep and cohesive slab forms. The thick rain crust from last weekend extends up to 1800m and is buried by 10-15cm of faceted snow. Snow pack depths and surface condition are highly variable in wind-exposed areas. Surface hoar buried 70 cms below the surface has been gaining strength, and just off the ground facets have been doing the same.
